The Mueller Thermal-Coil meter box allows water meters to be serviced, read and maintained, even though it is set deep into the ground to resist freezing. It is designed with the meter installed on a platform that normally sits near the bottom of the box, where the ground temperature keeps it warmer. The meter and platform are connected to the service line by coils of polybutylene tubing, which allow the meter and platform to be raised to the surface.
The body of the meter box is made from rigid PVC, which has a high insulating “R” value to resist frost bridging inside the box. For extremely cold climates, an optional insulating pad that traps the relatively warm air rising from the earth inside the box is available. Thermal-Coil meter boxes are shipped fully assembled and ready for meter installation. Their light weight saves shipping costs and makes installation a one-man job in most cases. Every box is factory-tested and has a 150-psig maximum working pressure rating.

Thermal-Coil meter boxes are available for 5/8- to 1-in. meters, with a wide variety of end connections, control valves, box depths, lids and other options. Due to the combination of features available, each box is custom-built to the project specifications.
